Warning (1) Dangerous liquid and surrounding When using pumps which transfer dangerous liquid or in potentially explosive atmospheres (only explosion proof type), make sure to perform the daily inspection not to leak liquid while observing the facility standards set forth by law. The pump operation under an abnormal condition like liquid leakage causes a tragedy like person injury, explosion or fire.

Caution (1) Prohibited on the unauthorized use Do not use pumps with a specification except for the indication on the nameplate. Install pumps after checking especially the motor specification (phase, voltage and frequency). Wrong use may cause personal injury or the pump and peripheral equipment damaged. (2) Restrictions on handler Carry, install, wire, operate and maintain pumps by experts who have full knowledge of pumps.
Unpacking check / Model description / Specification Check the followings and contact your supplier if there is any unclear. 1. The model, total head, capacity, motor specification and voltage on the motor nameplate comply with the ordered specifications. 2. All accessories are included. 3.

2. Piping load (1) Be subjected to a piping load by a pipe support. If it is possible for the piping to be expanded by high temperature liquid, the pump may be damaged by expansion. Therefore, install the extendable or flexible joint to prevent the load to the pump at the expansion.

(5) Check the rotating direction of the motor. If it is the three-phase power supply and the inverse rotation. Switch two wires of three wires. The direction is clockwise as viewed from the motor fan. Do not run dry. As the mechanical seal is cooled by pumped liquid through self-priming circulation, the operation with no liquid inside may cause the pump damage for heat.
Maintenance / Check Daily check (1) Check that there are no vibrations or any abnormal noises from the pump and the pump works smoothly. (2) Compare the current value during operation with the rated current value and check that the operating load of the motor is normal.

Assembly Assembly is the inverse of the disassembly. Clean the sliding parts and O-ring thoroughly not to adhere dirty or damage. Insert the mechanical seal during fitting the salient of the seal case with the ditch of the rotating ring, turn the phragm up and fit into the mechanical seal in the outside ditch of the seal case.
